摘要： In a method and apparatus for determining, in a system having a transmitting end and a receiving end, displacements of image features occurring between successively transmitted image sequences, by the operations of: determining, at the receiving end, peak values of pixel correlation between successively transmitted image sequences; deriving representations of estimated displacement values from the peak values of pixel correlation; and producing representations of optimized displacement values by a recursion operation which includes recursively deriving a correction value and adding the correction value to an existing estimated displacement value to form a new estimated value, the correction value is derived by performing a mathematical division operation in which the dividend is a selected function of pixel values in successive image sequences and the divisor is proportional to the average of a first value resulting from crosscorrelation of successively transmitted image sequences and a second value resulting from autocorrelation of the currently received image sequence.

摘要： In order to effect motion adaptive interpolation of nontransmitted television image sequences, each based on at least two transmitted television image sequences, the transmitted sequences are received and segmentally divided into stationary and moving components, and the displacement of the moving components is determined by picture elements. These operations are carried out by electronically segmentally dividing each sequence into background regions which are to become visible and background regions which are to become hidden due to the movement of each moving component and deriving characteristic segment information having four possible values; deriving a set of filter coefficients from the character segment information and from information obtained as a result of determining displacement; and applying the filter coefficients to a motion adaptive interpolation filter for causing the filter to generate the nontransmitted image sequences.
